AgroInsights- Foliar Treatments

June 3, 2023

With planting almost completed in much of the US, our thoughts turn to build upon the foundation created by our “at planting” fertilizer treatments!

Jay Castleman, Regional Sales Manager US East


Maximizing yield potential is all about providing soluble nutrient sources through contact with the plant during critical periods of growth, or in other words, empowering the crop.


One such treatment with great ability is Foliar Treatments! Too often, folks need to pay more attention to their ability to influence a crop through timely applications of nutrients applied over the crop. Such treatments allow the grower to support plant function, mitigate stress, and influence yield and crop quality. Most of the time, foliar treatments catalyze most nutrient programs.


I have always spoken of two absolute truths in nutrient utility: the value of a Soluble Nutrient Source and Crop Contact, two features that we can control, and a foliar application is the most efficient use of crop nutrients because of this fact. 


Think about it, where crop nutrients are concerned, everything we apply is done to create an impact on the crop or return on your investment. Well, if you compare the utility of foliar applications versus soil-applied applications or the effect that the soil-applied nutrient generates, the foliar application will win on most occasions.


For example, the impact that we can create with 20 pounds of Phosphorus applied to the soil, you can start with 1 pound of Phosphorus used as a foliar treatment. Along with that same principle, the same impact that you can generate with 6 pounds of Potassium applied to the soil, you can create with 1 pound of Potassium as a foliar treatment. Soluble nutrient making contact!


Beyond the advantage of nutrient utility comes timeliness. Empowering your crop before critical periods of growth can greatly influence such things as yield and quality in row crops. You can add value to such attributes as flavor, processing qualities, and shelf life of fruits and vegetables. 


NACHURS understands the value of foliar applications and has developed several products targeting such benefits. Many of these products are enriched with potassium, and not just any potassium but our NACHURS Bio-K® technology. Bio-K takes advantage of the most soluble form of potassium available in the market and pairs it with an acetate component creating an advanced potassium source.


Potassium plays many roles in crop production. Keep in mind that when it comes to nutrient transport into and throughout the plant, the potassium content within the crop, especially within the Guard Cells of the Stomata in the leaf structures, tremendously influences nutrient uptake. Those guard cells regulate the opening and closing of the cell structures and control, among other things, the process of Transpiration, thus, influencing osmoregulation and the vertical movement of nutrient sources into and throughout the plant. Simply put, good potassium content within the leaf can aid in the uptake of all soil resident nutrient sources. So yes, foliar treatments can not only add nutrient supply from the top but can also improve nutrient uptake through the root systems as well!


NACHURS has developed a full line of foliar products focused on our Bio-K technology, Nitrogen, Ortho Phosphorus, Micronutrients, and performance-enhancing additions such as Fulvic Acid. 


Soluble nutrient sources that make contact and empower your crop for maximum production. For help choosing the right foliar product, contact your local NACHURS dealer or sale representative.

We are at the point in the year where things are slowing down around the farm and it is time to reflect on the season to remind ourselves what we learned. Over the last couple of weeks, the District Sales Managers and I have spent some time reflecting on what worked well in the field and the challenges we faced too. Here are the top 5 things we learned from 2024 growing season: #1 Split applying Nitrogen and Sulfur is a practice that should be embraced on a yearly basis when growing corn. Do you remember how the planting season started and what happened in the first 60 days after the planters started rolling? Our field conditions started out dry with some areas of the corn belt showing up on the drought map. Then mother nature blessed us with rain that never stopped in some areas making it difficult to finish planting. Growers that had split applied their Nitrogen and Sulfur were able to avoid nutrient loss from the rain but also apply the nutrients when the crop needed it most. In the end yield was better on split applied nitrogen fields compared to fields that had all the N applied in the fall or spring before planting. #2 For the past 2 seasons in the North region, we have seen the benefits of adding NACHURS Humi-Flex FA to the in-furrow starter fertilizer. NACHURS Humi-Flex FA is our fulvic acid and it is becoming a valuable component in our starter fertilizer for many reasons. We are using it to chelate the nutrients in the starter fertilizer especially phosphorus. Humi-Flex FA also buffers the soil pH to neutral in that nutrient band keeping nutrients available in fields that have less then optimal pH for crop growth. Finally, we use Humi-Flex FA to create a healthy soil microbiome that leads to more root mass and nutrient uptake. #3 Nutrient uptake charts for corn and soybeans have been a great tool for our team to help our customers visualize the crops nutrient needs based on timing during the growing season.
